How can I programmatically scroll to a DataGridRow that's off-screen?

Posted By:      Posted Date: September 04, 2010    Points: 0   Category :WPF
There are many articles on the web about using attached behaviors for bringing a selected item into view (one such article is at http://www.codeproject.com/KB/WPF/AttachedBehaviors.aspx). I've been trying this technique to implement error navigation in an application (like double clicking on an error in VisualStudio) but I'm hitting a problem. While it works great when you click on a visible row, it doesn't work if the selected row is offscreen, since the DataGrid's VirtualizedStackPanel is virtualized, so the row container wouldn't have been created. I know that setting the DataGrid's VirtualizingStackPanel.IsVirtualized property to false will solve this problem (since it forces all DataGridRow containers to be created) but it ruins my application's performance. Is there another way to handle this so I can programmatically scroll to DataGridRows that are offscreen (and don't yet have containers)? In the worst case, perhaps a way to calculate where the row "would" be if I knew the row's index? Thanks, -Craig

How can i programmatically manipulate the Windows 7 on-screen keyboard osk: Move, Resize, Remove Tit


I'm working on an app where i want to display the built-in windows 7 onscreen keyboard in a 'always there' manner.  So i want to:

 1. Move it to a particular location

 2. Set it to a certain width and height

 3. Remove the caption/titlebar so the user can't move it around or close it

 4. Remove that abilty to resize it (or any other user adjustments for that matter).

Basically it just permanently sits there.  I've tried all the typical API functions (MoveWindow, SetWindowPos, SetWindowLong, etc...) but it refuses to work.  Code currently works with all other processes and apps (such as internet explorer and the command prompt); it's almost as if you can't apply anything to the osk.  What am i missing?  Thanks in advance.

Setting Screen Resolution

using the linqDataSource control programmatically (dynamically)



my scenario is this: I want to use the linqDataSource control to bind data to a gridview for it's efficient built-in paging and sorting features *but* I don't want the data to be bound until the user has input various search parameters, so I need to bind the data from a button click event. Also, the search options will be somewhat complex in that there will be several optional search parameters, via various dropdowns and textboxes, so I can't just declaratively/statically setup all the WHERE parameters on the linqDataSource (at least I'm assuming I can't, or that it may result in poor performance if I do and just assign default values like the everything wildcard '%' for the cases the user doesn't use a particular search parameter). Given that brief description, here is an example of what I'm doing, but with only one WHERE parameter for simplicity, the real code will be adding anywhere from 1 to about 12 WHERE parameters depending on how the user sets the search options in the GUI.

<asp:LinqDataSource ID="ldsMain" runat="server"

Detect Browser Screen Size??


Hi Everyone,  I need to detect the size of the user's screen for mobile devices (especially the BlackBerry). I've read a lot of pages that seem to refer me to the Request.Browser object, but I'm finding that this object doesn't have the correct values. For example, I have a BlackBerry and when I use the Request.Browser to get the screen size, it tells me it is 640x480. Well, I know it's not that big since an image of 300px wide just barely fits. Also, when I run on my desktop browser, it also says my screen is 640x480. I can assure you, it is not 640x480! ha!

  How does anyone reliably get the browser's screen size?? Do I have to revert to some kind of JavaScript? If so, where can I read more about it? Will it be any more reliable? Someone must have an idea about this. Thanks in advance!!

        Response.Write(currentCapabilities.ScreenPixelsWidth  + " <br>");


 but this is always show that the Height is 480 & the width is 640

He was at the end of a long consulting project and had several hundred Microsoft® Word documents, all of which required their document properties to be set identically, except the Title property of the document, which was to be based on the document file name, minus the .
